After Zhou Yunxi left the morgue, he hurried back to the Hou Mansion, and when he changed his clothes, he left through the back door of the Hou Mansion and headed towards the palace.

Others may not have any news about lead, but as the emperor of Great Chu, he should know a little bit about it. In the early years, the Emperor Taishang asked people to survey all the minerals in the territory of Dachu, how could he know about the 'lead' thing?

"Won't we be stopped in this way?"

Xu Ning still followed Zhou Yunxi, and An Yu stayed in the Hou Mansion to prevent trouble. In dealing with tedious things, An Yu is more handy than Xu Ning, and she handles it more appropriately.

"No, it won't." Zhou Yunxi shook his head, and the carriage was slightly bumpy because it was moving fast. In addition, in order not to attract attention, Zhou Yunxi did not sit in the best carriage in the Hou Mansion, but chose the most inferior, "They recognize me." ”

This is true, Zhou Yunxi went in and out of the palace frequently some time ago, and he was kind to Queen Liu Yue, but everyone who had some official positions in the palace roughly knew Zhou Yunxi's appearance.

As for whether he will be stopped at the gate of the palace-

In Zhou Yunxi's hand, there is a token that can enter and exit unimpeded. The token hadn't been used since Liu Yue gave it to her, because she wouldn't enter the palace if she had nothing to do, and she was summoned by Chu Ci when she entered the palace.

This is the first time in a long time that such an uninvited situation has occurred.

"The queen and the emperor have been waiting for you for a long time." Zhou Yunxi's carriage just stopped at the side gate of the palace, and the father-in-law standing at the side door hurriedly greeted him, "Please also invite the princess to come with our family." ”

This father-in-law, Zhou Yunxi, also recognized that his surname was 'Ma'. It was the big eunuch who was assigned to Liu Yue to help Liu Yue with after Chu Ci ascended the throne, and he was his confidant.

"It seems that the emperor and Niangniang have expected me to come here." Zhou Yunxi smiled when he saw him, and suddenly felt a little embarrassed, "I'm tired of my father-in-law." ”

"It is our family's honor to lead the way for the princess."

Ma Gonggong smiled, bent on his waist, respectfully.

Zhou Yunxi didn't say anything more, and led Xu Ning to keep up with Grandpa Ma's pace. Since Chu Ci and Liu Yue are already waiting for her, Zhou Yunxi will not delay time and grind and chirp.

After all, she is the only one who is most involved in this matter.

"I guess you've got the result." Before Zhou Yunxi could salute after seeing Chu Ci, Chu Ci spoke directly, and at the same time, Liu Yue motioned to Gonggong Ma to support Zhou Yunxi and prevent her from kneeling, "How?" ”

"Poisoning." Zhou Yunxi didn't ink, and opened his mouth straightforwardly. She looked at Chu Ci, her eyes were very clear, "These dead and sick people have one thing in common, they have been to a pharmacy in the south of the city. ”

"A pharmacy in the south of the city?"

Liu Yue frowned, as if she didn't quite understand.

She clearly remembered that almost all the pharmacies in the capital were under Zhou Yunxi's name, so what could be the problem with the pharmacies in the south of the city?

Naturally, Liu Yue thought about it, and she herself knew that most of the pharmacies in the capital were Zhou Yunxi's, not all of them were Zhou Yunxi's. If someone wants to do something and make some small moves on the plaque of the pharmacy, it will naturally be able to fool some unsuspecting people.

And the pharmacy in the south of the city took advantage of this.

"The pharmacy says 'Weekly Diary.'" Zhou Yunxi's eyes were slightly downcast, and his tone was a little gloomy, "The pharmacies under my name are all 'Zhouji Pharmacy', not a simple 'Zhouji'. ”

"Someone deliberately impersonated?"

Hearing this, Liu Yue also immediately reacted. As for Chu Ci, he took a sip of tea and didn't interject, just listening to Zhou Yunxi and Liu Yue talking.

"It's also deliberately guiding." Sanjiu Chinese Network

Zhou Yunxi replied in a deep voice, his face ugly.

"I asked Shizi to check the shop, but the shopkeeper is no longer there, and there are only conventional medicinal materials left in the pharmacy, and there are no foreign objects." Chu Ci only slowly spoke at this time, mentioning Qin Fengyi, "The prince should still be there now." ”

"Even if there is a foreign object, the people under the prince may not be able to notice it." Chu Ci's words made Zhou Yunxi shake his head slightly, "Your Majesty, do you know 'lead'?" ”

"Lead?"

Hearing this, Chu Ci's brows furrowed slightly. He stared at Zhou Yunxi, only thinking that this thing sounded familiar, but he couldn't remember where he had heard it.

At this time, seeing Zhou Yunxi's serious face, Chu Ci also roughly understood a little in his heart.

"Dead and sick people have something to do with this thing?"

"That's what caused it."

Zhou Yunxi replied quickly, and his tone was much more solemn. She looked at Chu Ci, saw Chu Ci frowning, and guessed that Chu Ci had no impression of lead.

But even so, Zhou Yunxi refused to give up.

"It's a mineral." Zhou Yunxi said for a moment, and suddenly remembered that he had ignored a little, "Your Majesty, you should know graphite, right?" Metallic lead is somewhat similar to graphite, but not identical. ”

"Graphite is known and used for writing and painting...... But this metal lead...... What is it? Chu Ci paused, showing that he didn't quite understand, "I found that sometimes the words of the princess are really difficult to understand. ”

"The emperor can understand that they are graphite poisoning." Zhou Yunxi was silent for a moment, knowing that what he said was not accurate, because Mu Cheng was already rolling his eyes frantically at this time, and let out a painful sigh, "In this way, the emperor should be a little more understanding." ”

"How can they eat graphite?"

Chu Ci suddenly remembered the lead at this time, when the Emperor Taishang was still the emperor, he had searched for mines, and there was another thing that was somewhat similar to graphite.

But it didn't know what it was for, and the gold and iron ore had not been refined enough, so they forgot about it. After all these years, it was the first time Chu Ci had heard someone mention that thing.

"If someone develops it into a powder and deceives the people that it is a medicine that can prolong life and promote health, someone will definitely be fooled."

Zhou Yunxi also said it clearly, and his eyes became more and more gloomy. The person who wanted to harm her was so mad that he used so many lives to stumble her!

I really don't have a troubled conscience!

"Your Majesty, the pastries that the mother asked for have been sent to the imperial dining room." Father-in-law's voice sounded at this time, breaking the sudden silence, "Look? ”

"Bring it in."

Chu Ci waved his hand, naturally he would not block the pastries outside. For Liu Yue's favor, Chu Ci is now more than ever. Zhou Yunxi is happy to see this kind of development, and he is even more happy to see it.

"There's lead in this pastry too."

When the plates of pastries passed in front of Zhou Yunxi's eyes, Mu Chengcheng suddenly made a sound, and at the same time, the light blue body also followed the maid with the pastries, and a pair of eyes never took a moment off the pastries.

"It's not small."

Mu Cheng was surprised, stopped, and turned his head to look at Zhou Yunxi.
